I constantly feel pretty tired. I try to get enough sleep, I work out regularly and I eat pretty well. I occassionally have a glass or two of wine with dinner, but my alcohol consumption usually is pretty low to moderate. What is wrong with me?

Get a sleep study to rule out sleep disorders, blood test for vitamin deficiencies, then look at things like stress or depression, exercise habits, etc. I have the same problem to some extent, but it has never felt severe enough for me to look into it. Also, I made a similar thread (use the search noob ): http://www.styleforum.net/showthread.php?t=13027

I generally only drink coffee during the morning, but I am known to have a red eye or some other type of espresso drink. It's rare that I have a second cup in the afternoon, but I've noticed that can go either way-- picks me up for a little while but then I feel very tired.
